'ZhcZZ do]; 0% it, may concern Be it knownthat I, Joi-rnL. llilOHUN, acitizen of the United States, residing at .Br0oklyn,.in-the county ofKings and State sofNew York, have invented new and useful Improvementsin Car-Roofs, of which the following is a specification.

Thisinvention relates to ear roof construction, and more particularly towhat is ioltnown as inside car roof structure in which theroofing'boards are located outside or above themetal root sheets.

.One of the objects of my present invention is to provide an improvedflexible sheet inetalroof construction which may be supported directlyupon thepurlins and ridge poleanddrain oventhe side plates of the car.

Another object isto provide improved zoaneans .forfsupporting theoutside roofing boards.abovethemetal roof at the eaves and at the ridgeof the car whereby the .root may be readily assembled and the boardssecured without nailing.-

Another object is to provide improved .meansior ventilation beneath themetal roof at theeaveqsofthe car.

:In the accompanying drawings: Figure 1 is .a transverse section of aportion of a car so roof embodying one term of my improvemerit; Fig. 2,a longitudinal section of the same, on a larger scale. taken at thecenter ofthe car ridge; Fig. ,3, longitudinal section through a portionof the roof, taken on d5- theline 3sof Fig. 1; Fig.3. a detail view ofthe bar for supporting the lower ends of the roofing, boards;-Fig. l, aside elevation of the carline hood and bracket; Figf 5, a horizontalsection of the same, :taken on the line 55 of Fig. 4, and showing theconnection with the lateral drain trough; Fig. 5, a perspcotiveview ofthe lower cnd ot the lateral drain trough; Fig. 6, a plan showing theconnections at the running board saddle, the running boards beingremoved; 7. a longitudinal sec-- tion of the ridge hood, and a portionof the roof at the end of the car; Fig. 8, an end elevation or" thesame, the running board b acket beingomittcd; and. Figs. 9 and it atransverse section anda side elevation, rcspcctircly. showing means forventilating beneath the metal roof sheets at the caves of the car.

The supporting frame work of the car .rootmay be constructed in theusual way by meansofcarlines, 20, supported on the side platesfll. andcarrying purlins, 24, and va ridge pole, 25,.the carlines,.purlins andridge. pole, being of any suitable or preferred construction.

According to one-feature of my-prescnt improvement, the metal roofsheets, .23, which extend froni the ridgeto the eaves of the car, aresupported directly upon the roof frame-work, and the upper and sideedges of said sheets. areturned up and over and down so. as to draininto drain troughs, 32, which .are located on the frame-work betweenadjacentedges. of the roof sheets and discharge over the side plate atthe. caves of the car. The lower end of each lateral drain troughisco'vered and held in place by a carline hood 60, bolted to the sideplate and havinglugs, 62 forengaging the ends of the sides of the draintroughs, 32, .as shown in l' 4 and 5, the bottom of the trough beingbent down and flared out at 32" bencatl the hood and over the side plateand facia hoard.

The runnin board saddle may be formed in twoparts, the lower castinghaving projections-2 7 and connc o-tiug respectively with the lateraldrain troughs, 32. and the ridge trough, '26, mounted on theridge pole,25, and an upwardly extending web. 29. to which the upper casting. 4-0,is bolted and supports the running" lwards. 41. The cast ing. 40, isalso provided with flanges for covering the ends of the lateral caps.22. and the ridge caps, as more fully set forth in. my eta-pendingapplication. filed December 21, 1911, Serial No. 667.069.

In the present instance. the metal root. construction is locatcildirectly upon the frame work of theroof and the water which collccts inthe ridge trough and lateral drain troughs from the roof sheets drainsthrough the discharge from said troughs over the side of the car...

For the purpose of supporting the roofing boards. 30, above the-metalroof sheets and caps, I provide a bracket. 6]. at the eaves as shown inFigs.

upper ends of the boards, an inverted "t" bar, 43, may be supported onlugs formed on the running board saddle, 40, the ends of the boardsbeing covered and held in place by a bar or ke block, 42, which is alsocar-led upon and between lugs cast upon the side of the saddle andbeneath the running boards.

The ridge hood, 66, has a vertical arm list, which mav be fastened tothe running board, 41, for giving the hood greater stability inassisting to support the outside roofing boards, for which purpose itmay be provided with lugs, 65, for holding one end of the 'l' bar, andlugs, 67, carrying the end of the hey block, 42. The hood, 6'6, may alsobe formed with interior lugs, 63, for holding the ends of the sides ofthe ridge trough, 26, the bottom of which is bent down and flared out at26, over the end facia board, 7 and 8. The hood, 66

also covers the end of the ridge cap, 35, and

. means the is bolted to the end plate of the car.

In order to improve the ventilation of the interior of the car, notchesor passages, 70, in the side plates, 21, and corresponding passages, 71,in the top of the facia board, 58, may be provided beneath the roofingsheets, 23, which are bent down over the side plate and top of the faciaboard and are fastened to the side plate by means of bolts, as shown inFigs. 9 and 10 of the drawings. lily this fresh air may pass freelythrough said notches or passages into the interior of the car beneaththe metal roof, thereby ventilating and cooling the same and at the sametim excluding any rain or moisture.

.lVhile mv improvement is shown as up plied in connection with outsideroofing boards, it. is to be understood that the to tures relating tothe flexible metallic roof construction supported directly upon the roofframe-work may be used independently, and the outside roofing boardswith their supports be dispensed with, if desired,

- will be evident.
